Abstract
A method of preparing insoluble transition metal compound particles is described, comprising: providing a transition metal salt solution having the formula (TM)(S) wherein TM is one or more of Mn, Ni, Co, Mg, Zn, Ca, Sr, Cu, Zr, P, Fe, Al, Ga, In, Cr Ge or Sn; providing a source of a carbonate-, hydroxide-, phosphate-, oxyhydroxide- or oxide-based anionic compound wherein the anionic component, represented by S', is reactive with TM to form the particles; adding the transition metal salt solution and anionic compound to a reaction chamber; and subjecting the chamber to sonication at an intensity of about 0.1 to about 50 W/mL. In an exemplary embodiment, MnCOparticles are formed from: MnSO; and NaCOand/or NHHCO, wherein the ratio of MnSOto NaCOand/or NHHCOis from about 1:1.5 to 1.5:1. The particles may have narrow size distribution and a tap density of about 1.7-2.3 g/mL.
